Using dlls with compact framework - Error 80040154

[A.P.Gumby]

Hi,
I seem to be asking a lot of questions lately but I have only fairly recently started using .net and now have a Windows CE application to develop.

So, I am using VB on VS2005 to develop the Windows CE application and I want to re-use some VB6 dlls that I have been using for years.

The dll is called DEF100 and in a standard windows application I would include it as a project reference and then use it as follows.

Dim objDefinitionFile As Object
        
        objDefinitionFile = CreateObject("DEF100.Definitions")
        clsSpecParameter.shoMaximum = objDefinitionFile.iMaximum

The above works just fine. My problem comes when I am now trying to use the same dll in the compact framework.
It appears that the CreateObject method does not exist.
I have tried to use

Dim objDefinitionFile As New DEF100.Definitions

but get a "COM object cannot be created ..... error 0x80040154"

Any help appreciated.

Hi,
you can't use VB6 dlls on the compact framework, as it is a different architecture - compiled for x86, not ARM

Thanks for the reply,
I can't believe I was that stupid.
Of course, I am going to have to build my dlls as CE applicatons before I can use them.
That must be a pain for anybody who has legacy dlls that they want to use in their application but do not have the source code.
In that case, I guess that the answer would be to use XP embedded.

I really appreciate the help you have been giving me here Pete.
This forum seems a little quiet compared to other areas on VBForums.
Is that usual?
